BED-BOTTOM FAIBBIQ.

T all whom it may concern:

Be it known that CI-IAELESB. FRALEY, citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, has invented certain new and useful Improvements in Bed-Bottom Fabrics, of

' which the following is a specification I on the facility with which the unit parts can be formed and assembled from the constituent elements enterin into the structure and b the convenience with which it may be at-- tached to the supporting-frame, as will be hereinafter set forth in detail.

The fabric is composed of a series of straight longitudinal wires or rods extending lengthwise of the frame and disposed at intervals across the width thereof, and a series of zigzag wires also running lengthwise and alternately looped around two contiguous units of the straight series and presenting a diagonal appearance'and forming a diamond fabric.

In the drawing, Figure l is a plan of a bed bottom embodying the improved features. Fig. 2'is a detail of the end and intermediate connections of the wire units; and Fig. 3 is a detail showing the assembled relation of one of the zigzag units and the longitudinal fabric Wires.

A may represent the companion side rails and B the end rails which form the usualsupporting frame to which the bed-bottom fabric is attached. In this instance the elastic fabric consists of a number of straight longitudinal wires or rods 4 and a series of zigzag wires 5 and 6 interwoven therewith and gunning the full length thereof, as shown in The reference numeral 4 indicates the longitudinal wires, and the numerals 5 and 6 indicate the zigzag wires and refer to the same as the whole number, but other numerals will be used in specifically referring to individual parts for the purpose of making the constructionfeaturesclear.

wires 4 are provided at their respective ends with loops or eyes 7 which in their turn engage the inner loop ends 8 of a series of helical tension springs 9 connected to the loo ends 7 of each alternate straight longitudina wire 4. The outside ends 10 of the springs 9 are secured in the respective end rails.

One end of the outside diagonal wire 5. connects with the upper loop end 7- of the outside longitudinal wire 11, of the series 4. From this upper loop end the wire 5 runs Patented Dec. 3, 1907.

inward diagonally with a half interlock turn 13 around the next straight wire 14, of the series 4, and then outward diagonally with a half interlock turn 15-around the outside wire 11, and so on alternately until the oppo' site or lower end is reached when the terminal end of the zigzag wire 5 is secured in the loop end 7 of the outside straight wire 11. The next zigzag wire 6 starts from the upper loop end 7 of the third straight wire 4, the

first diagonal section thereof running out-- ward with an interlock or half loop turn 16 around the strai ht wire 4, then diagonally back to and with a half turn 17? around the third wire 4 from the edge, and so on back and forth until the end of zigzag Wire (Sis secured in the loop end 7 of the third straight wire 4. This description of the interwea features of two companion zigzag w'ires v v il l apply to all alike throughout the structure in forming the diamond design shown.

It will be notedbyreference to Fig. 2, that the zigzag wires extend around the longitudinal wires I from opposite. directions in maintaining a symmetrical shape. It will further be seen that the zig-zag wires in looping about the wires 4 dojnot interlock with each other, the loopsgbeing entirelyindependent of each other. By this arrangement the junction of the longitudinal and zigzag wires is movable instead of fixed so that the zigzag wires have a free sliding movement on the longitudinal wires in conforming to any changdwhemsuljected to a load orpressure whether equally distributed over the surface or not. When the wei ht or pressure is removed the parts quio y I what I o aim is thus described my invention, 7
